PEELIMIXARY CLASSIFICATION OF SCOLYTOIDEA. 223 



without sutures; eyes oblong, elliptical, deeply emarginate; anterior 

 tibia strongly narrowed to apex, with submarginate row of closely 

 placed teeth on the ventral side; elytral declivity Avith many closely 

 placed marginal teeth; lateral margm of pronotum acute, anterior 

 margin without serrations. Type of genus, Wehhia dijjterocarpi new 

 species. 



This genus is named for Mr. J. L. Webb on account of the large 

 number of scolytoid beetles collected by him during his brief employ- 

 ment in the Philippine service. 



Webbia dipterocarpi n. sp. 



Length, female type, 3.1 mm. Subelongate; pronotum and all 

 but the dechvity of the elytra light ferruginous, the declivity black. 

 Pronotum with anterior area swollen, opaque, nearly smooth; apex 

 steep, subtruncate, and fineh^ rugose; median and posterior areas 

 smooth, subopaque, and. very finely punctured. Front moderately 

 narrow, subconvex, opaque, \^dth fine median line. Elytra to near 

 declivity smooth, shming, with fine, closely placed, and confused 

 punctures with no trace of stria, narrow, and near vertex slightly 

 swollen, densely opaqne, nearly black; declivity steep, flat, opaque; 

 interspace 1 elevated, smooth; interspaces 2 and 3 each with straight 

 rows of granules; margin from vertex to apex armed each side with 

 10 closely placed serrations or teeth, becoming slightly larger toward 

 apex. These teeth evidently represent the 10 interspaces of the 

 normal elytra. Near Pagbilao, Philippine Islands, m wood of dead 

 log of Dipterocarpus grandiforus Blco., August 7, 1903. J. L. Webb, 

 collector. Under his number 94c. 



Type. — Cat. No. 7406, U. S. National Museum. 



Length, male type, 2.6 mm. Subelongate; pronotum slightly 

 broader than elytra which are narrowed toward declivit}', light 

 ferruginous throughout. Head narrow, shinmg, with deep epis- 

 tomal impression and a slight posterior impression. Pronotum 

 opaque, finely rugose throughout, with distinct median impressed 

 shining line to anterior declivity which is steep and strongly retuse 

 to anterior margin, sides slightly narrowed from anterior angles to 

 base, lateral margins subobtuse; elytra with sides slightly narrowed 

 toward declivity, shining, punctured as in female but with strife evi- 

 dent and faintly impressed; declivity steep, fl^at, opaque, rugose, 

 but without elevated interspaces, margin with but seven marginal 

 teeth, coarser toward vertex and arranged in groups of 3-2-2. In 

 a lateral aspect the dorsal line forms a broad curve from the mandi- 

 bles to the apex of the abdomen. From same colony as the female. 



The smaller size and general appearance of the male suggests 

 afiinities with the Xyleborus group but it is radically different in all 

 of the more important characters.
